Quick fix: If your microwave is running, but not warm, and it makes a buzzing noise, then the magnetron can be an issue. To change this you will need a professional technician.

2. High-voltage diode failure

The high-voltage diode carries the magnetron forward by converting AC voltage into DC. If it fails, the magnetron does not get enough power to generate heat.

Quick Fix: You can test the diode using a multimeter, but handling high-voltage components can be dangerous. It’s best to call an expert for microwave repair.

3. Faulty door switch

The microwave has several door switches that prevent them from running when the door is open. If any one of these switchs to a malfunction, your microwave can still stop heating while still appearing to work.
Quick Fix: Try to open and close the microwave door. If it still does not heat up, a door switch may require replacement.

The capacitor and transformers work together to promote voltage for magnetron. If any of them fails, your microwave does not heat up.
Quick fix: These parts keep high-voltage electricity even when it is unplaced, so it can be dangerous to try DIY fix. It is best to call a microwave repair specialist.

6. Power supply problems

Sometimes, the problem is not with your microwave but with a power source. A weak or defective power supply can prevent the microwave from heating properly.

7. Control board failure

The control board manages all the functions of your microwave. If it is damaged, microwaves can prevent heating, even if other functions, such as timer and lights, still work.
Quick Fix: If you have checked everything else and your microwave is not heating food, the control board may need to be replaced by a technician.
